The concept of entropy metrics and its relevant principles, mainly the estimation of the effect of negative entropy flux
on the self-organization of atmospheric systems are reviewed. The principle of the non-equilibrium thermodynamics,
as well as their possible applications to geospace physics are discussed too. The high-resolution measurements of the
spectral solar irradiance at the top of the Earths atmosphere by the Solar Radiation and Climate Experiment (SORCE)
satellite are used to examine the magnitude and spectral distribution of the Earths entropy flux from the TOA
incident solar radiation. A future space mission CLARREO proposed for highly accurate decadal change observations
sensitive to the most critical climate radiative forcings is reviewed. The analysis of negative entropy flux, based on
satellite data, which is able to provide a new insight into the mechanism responsible for the evolution of a tropical
cyclone system as well as a new approach to predicting its intensity trend, are given.
Keywords: non-equilibrium thermodynamics, entropy flux, anomaly of geophysical fields, tropical cyclones, diagnostics of atmospheric catastrophe
